What is 'fart walk', the new gut health hack that is going viral?

Coined by Canadian cookbook author Mairlyn Smith, the term 'fart walk' describes a short post-meal stroll to ease digestion and reduce bloating. Popularised on TikTok, the trend humorously highlights a practice long rooted in global traditions, including India’s. Smith began these walks with her husband after fibre-heavy dinners — blending wellness with a touch of humour.
